Full title and description

St ASTM RR-F01-1019 2008 — Research Report RR:F01-1019, published by ASTM International in 2008. The report documents an interlaboratory study performed to support the precision statement for ASTM test method F2360 (Standard Test Method for Determining Luminance of a Membrane Switch Backlit with a Diffuse Light Source).

Abstract

This research report summarizes an interlaboratory study conducted by six laboratories that tested three lamp sources in order to establish repeatability and reproducibility (precision) data for test method F2360. The findings supply the statistical precision statement used to qualify and interpret F2360 measurement results.

Scope

The report's scope is limited to presenting the design, execution, and statistical analysis of an interlaboratory study whose goal was to produce a precision statement for ASTM F2360 (luminance measurement of membrane switches backlit by diffuse sources). It documents test samples (three lamp types), participating laboratories (six), measurement protocols used to align with the F2360 procedure, and the resulting repeatability/reproducibility statistics. The report is intended to be used alongside the F2360 test method to interpret measurement uncertainty and conformity.

Key topics and requirements

• Interlaboratory study design and protocol for photometric luminance measurements.
• Test specimens and lamp types used to represent typical backlighting sources.
• Statistical analysis to derive repeatability and reproducibility (precision) values for F2360.
• Measurement conditions and alignment with F2360 procedural requirements (ambient light control, detector orientation, source stabilization).
• Recommendations for laboratories on applying the precision statement when reporting F2360 results.

These topics are presented to support consistent application of F2360 in product testing and inter‑laboratory comparisons.

Typical use and users

Users: test laboratories, product manufacturers (membrane switches and backlighting suppliers, e.g., LED or EL suppliers), quality assurance personnel, standards committees, and accreditation bodies. Typical uses include validating laboratory capability to perform F2360, verifying measurement uncertainty for product specifications, and providing evidence for product claims about luminance of backlit membrane switches.

Related standards

Directly related: ASTM F2360 (Standard Test Method for Determining Luminance of a Membrane Switch Backlit with a Diffuse Light Source). Other related membrane‑switch test methods and guides (e.g., F2359 for color of backlit membrane switches and other F01 subcommittee methods for membrane switch electrical/physical testing) are commonly used in conjunction with F2360.

FAQ

Q: What is this standard?

A: This item is a research report (ASTM Research Report RR:F01-1019, 2008) that documents an interlaboratory study intended to establish the precision statement for ASTM test method F2360 (luminance measurement of membrane switches backlit with a diffuse source).

Q: What does it cover?

A: It covers the interlaboratory study design, participating laboratories and samples (three lamp types), measurement procedures aligned with F2360, statistical analysis, and the derived repeatability and reproducibility figures used to accompany F2360 test results.

Q: Who typically uses it?

A: Test laboratories performing photometric measurements on membrane switches, manufacturers of membrane switches and backlighting, QA/QC teams, and standards/committee members who need documented precision data for comparative testing and specification compliance.

Q: Is it current or superseded?

A: The research report was published in 2008 and remains the published interlaboratory record (RR:F01-1019). The associated test method designation appeared as F2360-08; some publicly available records indicate the 2008 edition may have later been withdrawn or superseded—users should check ASTM International for the official current status of F2360 and any successor documents before relying on it for regulatory or contractual work.

Q: Is it part of a series?

A: It is a stand‑alone ASTM research report tied to Committee F01 work on membrane switches (developed by Subcommittee F01.18) and intended to accompany the F2360 test method; it is part of ASTM's practice of publishing research reports to document interlaboratory precision for specific test methods.

Q: What are the key keywords?

A: Luminance, membrane switch, backlight, diffuse light source, interlaboratory study, precision statement, repeatability, reproducibility, ASTM RR:F01-1019, F2360.
